And novelty, in fact, is one of the forces that has driven Record Store Day to be such a popular annual event for hardcore music geeks (at least those still attached to physical media). For those not aware of RSD, it’s a once-a-year event with a fun and noble purpose: to bring attention to the time-honored ritual of shopping (browsing the bins and mingling with fellow music geeks) in an actual, brick-and-mortar, independently owned record store. Since its founding in 2007, though, RSD has also become a can’t-miss day for collectors, as artists both indie and mega–and across all genres–release limited-edition, one-of-a-kind singles and albums, many of which sell out within hours.
